I'm liking the name. The advice I have today is to add to what previous comments have said about a character's biography. Void is a very open-format place (this goes for character design and world creation too) so you do it the way you like, don't worry about being told off for doing it wrong.
Mine, for example, consist of:
1.) a series of bird chirps and angry screeching
2.) a military dossier that indirectly tells the audience about the character while making an entertaining reading experience
So go ahead and get creative!
